Bij AGN 3D hebben ze een artikeltje in elkaar gedrukt waarin ze uitleggen hoe je je CPU kunt 'lappen'. Hmm ja, klinkt nogal wazig. Wat ze bedoelen is dat je de bovenlaag van je CPU behuizing met (fijn) schuurpapier wegschuurt, waardoor het oppervlak vlakker wordt en de warmte geleiding wordt verbeterd:
Once the CPU shows signs of wear in the center then switch to the next highest grade of paper. The first part of the process will take a while about 20-25minutes depending on how bad the CPU is and what grit paper you started with. At this point some people may ask why can’t I use coarser grit of paper to start with? The reason I don’t recommend that is the coarser the grit you start with the more likely the edges of the CPU will become beveled. At the beginning of the sanding process the paper will “grab” the CPU there and rock the unit to the side first and remove more material than you want as your sanding it down.
